* [SPARK-12324][MLLIB][DOC] Fixes the sidebar in the ML documentationTimothy Hunter2015-12-164-34/+149
| | | | | | | | | | | | | | | | | | | | | | | This fixes the sidebar, using a pure CSS mechanism to hide it when the browser's viewport is too narrow.

* [SPARK-9026][SPARK-4514] Modifications to JobWaiter, FutureAction, and ↵Richard W. Eggert II2015-12-157-158/+251
| | | | | | | | | | | | | | | AsyncRDDActions to support non-blocking operation These changes rework the implementations of `SimpleFutureAction`, `ComplexFutureAction`, `JobWaiter`, and `AsyncRDDActions` such that asynchronous callbacks on the generated `Futures` NEVER block waiting for a job to complete. A small amount of mutex synchronization is necessary to protect the internal fields that manage cancellation, but these locks are only held very briefly and in practice should almost never cause any blocking to occur. The existing blocking APIs of these classes are retained, but they simply delegate to the underlying non-blocking API and `Await` the results with indefinite timeouts.

All the tests pass even if the filters are not pushed down due to Spark-side filtering. In this PR, Firstly, I corrected the tests to properly check the pushed down filters by removing Spark-side filtering. Also, `!=` was being tested which is actually not pushed down. So I removed them. Lastly, I moved the `stripSparkFilter()` function to `SQLTestUtils` as this functions would be shared for all tests for pushed down filters. This function would be also shared with ORC datasource as the filters for that are also not being tested properly.

This PR change to generate a single plan (three aggregations and two exchanges), which work better in both cases, then we could safely remove the flag `spark.sql.specializeSingleDistinctAggPlanning` (introduced in 1.6). For a query like `SELECT COUNT(DISTINCT a) FROM table` will be ``` AGG-4 (count distinct) Shuffle to a single reducer Partial-AGG-3 (count distinct, no grouping) Partial-AGG-2 (grouping on a) Shuffle by a Partial-AGG-1 (grouping on a) ``` This PR also includes large refactor for aggregation (reduce 500+ lines of code) cc yhuai nongli marmbrus Author: Davies Liu <davies@databricks.com> Closes #10228 from davies/single_distinct.

* [SPARK-11497][MLLIB][PYTHON] PySpark RowMatrix Constructor Has Type Erasure ↵Mike Dusenberry2015-12-111-1/+1
| | | | | | | | | | | | | | Issue As noted in PR #9441, implementing `tallSkinnyQR` uncovered a bug with our PySpark `RowMatrix` constructor. As discussed on the dev list [here](http://apache-spark-developers-list.1001551.n3.nabble.com/K-Means-And-Class-Tags-td10038.html), there appears to be an issue with type erasure with RDDs coming from Java, and by extension from PySpark. Although we are attempting to construct a `RowMatrix` from an `RDD[Vector]` in [PythonMLlibAPI](https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/api/python/PythonMLLibAPI.scala#L1115), the `Vector` type is erased, resulting in an `RDD[Object]`. Thus, when calling Scala's `tallSkinnyQR` from PySpark, we get a Java `ClassCastException` in which an `Object` cannot be cast to a Spark `Vector`. As noted in the aforementioned dev list thread, this issue was also encountered with `DecisionTrees`, and the fix involved an explicit `retag` of the RDD with a `Vector` type. `IndexedRowMatrix` and `CoordinateMatrix` do not appear to have this issue likely due to their related helper functions in `PythonMLlibAPI` creating the RDDs explicitly from DataFrames with pattern matching, thus preserving the types. This PR currently contains that retagging fix applied to the `createRowMatrix` helper function in `PythonMLlibAPI`. This PR blocks #9441, so once this is merged, the other can be rebased. cc holdenk Author: Mike Dusenberry <mwdusenb@us.ibm.com> Closes #9458 from dusenberrymw/SPARK-11497_PySpark_RowMatrix_Constructor_Has_Type_Erasure_Issue.
